Define Doppler Effect
The apparent change in the frequency of a wave due to the motion of the source or observer

Label This Diagram
The Doppler Effect
a - observer
b - source
c - crest 1
d - crest 2
e - crest 3

Label This Formula
The Doppler Effect
f’ - apparent frequency
c - speed of wave / light
f - actual frequency
v - speed of source
+ - moving away
- - moving towards

Name 2 uses of the doppler effect
Garda speed guns
Red shift of stars to measure their speeds
Demonstrate the doppler effect • 1
Mount bicycle wheel on a frame
Attach buzzer of a single frequency and a battery to the rim
Demonstrate the doppler effect • 2
Turn on buzzer
Observed frequency = source frequency
Demonstrate the doppler effect • 3
Spin wheel quickly
Observed frequency increases and decreases - Doppler effect
